You are a great dungeon lord. You own darkness and countless treasures. But fabulous creatures coveted your possessions! Stop them with traps and a huge amount of explosives! Traps are built for gold and abilities require magic crystals.
After every wave of enemies you can choose one from 3 random upgrades. Some open up new possibilities, and some improve existing ones.
Enemies are cunning, they are not only able to heal others, but also have different properties.
Defeat all stupid invaders, these treasures are yours!
